The syndrome of insulin resistance (IR) is one of the leading reasons for the increased risk of cardiovascular diseases and their complications. Among the key components of IR are obesity and dyslipidemia. Hydroxycitric acid (HCA), an inhibitor of a key enzyme of lipogenesis ATP citrate lyase (ACLY) is a promising obesity treatment agent. The aim of this work was to investigate the effect of HCA on lipid and lipoproteins content in the blood serum, as well as lipid content and activity of some lipid metabolism enzymes in the liver of hamsters with IR. IR was modeled by keeping animals on high-fat diet with addition of fructose. Lipid content was determined by using standard reagent kits, the level of lipoproteins, the activity of glucose 6-phosphate dehydrogenase and ACLY – spectrophotometrically, lysosomal lipase activity – fluorimetrically. Development of hyperlipidemia and atherogenic dyslipidemia, lipid accumulation in the liver, activation of lysosomal lipase and ACLY and reduction of glucose 6-phosphate dehydrogenase activity were shown under IR. The treatment by HCA reduces the manifestations of hyperlipidemia, but enhances the lipid accumulation in the liver.
